Function Documentation

uint8_t* hash_final ( Hash * h ) [inline]

Finalize the hash computation and return the digest.

Note:: This function must be called exactly once per each computation. Calling it twice leads to undefined behaviour.; The pointer returned is within the hash context structure h, so it has the same lifetime as the hash instance. The data will be invalidated as soon as hash_begin is called again on the same instance.
